New fun while sitting

Impressed by other reviews I had bought for our administration two stool for testing purposes. I myself have an in use and I will keep. Great seat feel you are always on the move and can constantly try new poses, which I personally like a rocker. The tire could smell the first few days something strictly for rubber, but that is now gone.
As a disadvantage we can only say that precisely the roles are missing in order to work better at the desk can. So the radius is rather limited.
